To'aZZ whom it may concern:

Be it known that 1,. Louis B. SMYsnn, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Gasement-Window Operators, of which the following is a specification.

This invention relates particularly to cer tain improvements in casement window operators, the particular object of the invention being to provide a mechanism of the ance with my invention, installed ready for use, a portion of the sill being broken away to show the arrangement of the parts. Fig.

'2 is a cross sectional view of a portion of a typical window construction, and showing the installation of the mechanlsm. Fig. 3' is a group view showing the various parts of the mechanism detached. Fig. i is a plan view of the mechanism assembled ready for installation.

In the drawings, a denotes generally the window frame, and b the sill within which the operating mechanism is located; 0 is the sash carried as usual on suitable vertical hinge supports; d represents a screen posi-. tioned inside the sash; 6 denotes an operating shaft extending from the mechanism to the inside of the frame and having an operating handle f, by means of which the sash can be moved through the mechanism without moving, disturbing or working through the screen or any other device which may be located in the frame inside of the sash.

The operating mechanism comprises a housing 1, located in a. recess in-the frame and held in position as by the screws 2. The housing is chambered in its upper face, as at 5, and transversely apertured as at 6. This aperture opens into the chamber in' order that a gear in the chamber may mesh Specification of Letters Patent.

with a pinion located in this transverse aperture, Within the chamber is located a gear 10 preferably of the worm type, seated in a proper bearing in the bottom of the chamber and supported at its upper side in the annw l'ar cover 7, which closes the chamberbut permits of effecting a driving connection with the gear. .The transverse aperture is enlarged at one side of the housing to permit of the entrance. of the pinion 15, one end of the shaft, 16, being supported'in the wall of the housing as at 3, the other end of the shaft, 17, being supported in the bushing 20 fitting within the enlarged aperture. Both ends of the shaft are exposed and have squared sockets to receive the operating shaft e, in orderthat the same housing may be used either for a right or left hand sash.

The bushing is held in position by the, taper pin 21. The sleeve 25 has a reduced end 26, fitting within the aperture in the cover, and a fin 27 which'may be driven down into the sill to prevent the rotation of the sleeve. This sleeve provides a bearing for theconnector 30, which at its lower end has a driving engagement with. the gear 10,.and at its upper end with an actuating lever 35, where it fits within an aperture 36 in the lever, which aperture is traversed by a cross web 37 which fits within a groove 31 in the upper end of the connector. The other end of the lever is provided with a stud 38 upon which is mounted a roller 39, which travels in a slot 40 in the plate 41 which is fastened to the underside of the sash.

By reference to Figs. 1 and 2 seen that the axis of the gear and connector is preferably locatedcentrally' of the width of the sash and close to the axial line of swing thereof in order that as the sash is swung by the lever th'elatter is substantially concealed from view in all positions of-tho sash, and when the sash is closed the lever is wholly concealed from view. This also a small operating handle fitted closely to the frame within the room, although of a will be course it is apparent that where the frame is covered, as by a radiator or other device, theoperating shaft e can be extended so placed in any conorder that the chamber may also act as a reservoir for lubricant, the connector being providedwith an oil hole 38 and outlets 34:. The complete operating mechanism is very compact; the construction avoids the necessity of making separate housings for right and left hand sashes; it is susceptible of economical manufacture, and is extremely eflicient in its operation. The use of the connector permits of adapting the principal parts of the mechanism to varying conditions by the substitution of connectors of difierent lengths.

I am aware that the structure herein illustrated and described is susceptible of various modifications and alterations without departing from the spirit of the invention as set forth in the appended claims. Also, that the use of this mechanism is not necessarily limited to casement windows, but can be adapted for use with other structures of a similar character.

"I claim as my invention 1. The combination with a window frame or the like and a swinging closure therefor, of a housing located in a recess in the sill of said frame, a chamber formed in the upper side of said housing, a gear mounted therein, an annular cover for said chamber, a sleeve seated at its lower end in said cover, a connector supported by said sleeveand having a driving engagement with said gear, an actuating lever in driving engagement with the upper end of said connector, operativeconnections between said lever and closure, a pinion mounted in said housing in mesh with said gear, and an operating shaft therefor.

2. The combination with a framed opening and a closure therefor mounted to swing' on vertical hinges'upports, of an operating mechanism for said closure, comprising a housing located in a recess in the bottom of the framed opening, a gear mounted therein on a vertical axis located at approximately the central plane of the closure, an actuating lever operatively connectedwith the closure, a connector interposed between and having driving engagement with said lever and gear and non-integral with either, a pinion mounted in said housing in mesh with said gear, and an operating shaft for with either, and a sleeve within which said connector fits, and has its bearing.

4. In an operating mechanism of the char acter described, a. housing having a chamber in its-upper side, a gear located 1n the chamber, an annular cover for said housing forming'a bearing for the upper side of said gear, a separate sleeve having a reduced end fittmg within said cover and formlng a shoulder resting thereon, a connector fitting and having a bearing in said sleeve, a driva ing engagement between said connector and gear, a lever in driving engagement with the upper end of said connector, and means for fastening together said lever, connector, sleeve, gear and cover.

5. An operating mechanism of the character described, including a housing having achamber in the upper side thereof and a transverse aperture enlarged in one wall of said housing, a gear mounted in said chamber, a pinion mountedin said aperture in mesh with said gear, a pinion shaft having one end located in the aperture in one wall of the housing, a bushing located in the enlarged aperture in the other wall of the housing and constituting a bearing for the opposite end of the pinion shaft, an end of said pinion shaft belng exposed and adapteg for driving connection with an operating s aft.

6. An operating mechanism of the character described, including a housing pro-- videdwith a chamber in its upper side and a gear mounted therein, a transverse aperture in the housing communicating with said chamber, a pinion mounted therein in mesh with said gear, a stub shaft at either end of said inion, one of said shafts being adapted to ta e a bearing in the aperture inpne wall of the housing, a bushing fitted in the enlargedaperture in the opposite wall of .the

housing and providing a bearing for the shaft at the other end of the pinion, and

means for securing said bushing in place.
